All data were used in the factorAnalysis1.1.html document you already received.
A series of factoro analyses were run on all items in the file factorAnalysis1.1.html. THe literature suggests doing this so you can compare both statistical measures of how well it fits, and also how logical the grouping of factors is according to knowledge of the subject.
This set of analyses showed that some items had really low communalities, meaning that they didn’t covary much with any of the other items. This means they will not be robust parts of any factor, and they recommend that you remove these from the analysis.
Models with different numbers of factors had different numbers of items with communalities less than 0.4. So a new data set was made for each number of factors, with only the items with communalities of 0.4 or larger.
Because each number of factors require a different data set (different numbers of items), all the steps had to be rerun sstarting with imputation. Those are the models included in this document.
Testing analyses from 11 - 18 factors.
include reference on why imputation is better than removing observations, pairwise removing is biased, using means isn’t good.
Categorical missing values using multiple Correspondence Analysis (also called Missing Fuzzy Average method) Josseet al (2010)
This function tests whether a correlation matrix is significantly different from an identity matrix (Bartlett, 1951). If the Bartlett’s test is not significant, the correlation matrix is not suitable for factor analysis because the variables show too little covariance.
This is a test that the matrix is an identity matrix. This would mean that the correlations were not significantly different from 0. If it’s not significant, the matrix is not suitable because the variables show too little covariance.
The chi-squared for the Bartlett test is 6.4178359^{4} with 2211 DF, p = 0e+00.
From EFAtools::KMO documentation:
The KMO represents the degree to which each observed variable is predicted by the other variables in the dataset and with this indicates the suitability for factor analysis
The numeric version of the dataset is used because stats::cor is used to find the correlation and it requires numeric input. Used option for Spearman correlation because of ordered variables.
## ℹ 'x' was not a correlation matrix. Correlations are found from entered raw data.

For factor analysis, it is recommended that some of the item
correlationsshould be between 0.3 and 0.9. Polyserial correlations were
computed using the lavCor function in the
lavaan package in R with options for ordered factors and
pairwise handling of missing values. Pairwise deletion of missing values
means that individuals with some missing data are not dropped; their
data is used when available.
The minimum correlation in this data set is -0.7175718. The maximum correlation in this data set is 0.8869939.
#### Post-Imputation
The post imputation polyserial correlation was also computed using
the lavcor function, but with no setting for missing values
since they were imputed and cor.smooth = TRUE to avoid having a
non-positive-definite matrix to work on in future steps.
The minimum correlation was -0.6902268. The maximum correlation was 0.8853661.
From the EFAtools documentation:
Various methods for performing parallel analysis. This function uses future_lapply for which a parallel processing plan can be selected. To do so, call library(future) and, for example, plan(multisession); see examples.
Settings Used:
- n.obs = 1117 - eigen_type = “EFA” - fa = “fa” (factor analysis not
PCA) - fm = “wls” (weighted least squares because pa gave errors and
weighted recommended for ordinal data. - use = “all.obs” (since we have
imputed missing values, we can use all data points) - cor = “poly” (use
polychoric correlation matrix) - n.iter = 100 (run for 100
iterations)
The suggested number of factors is 16.
MAP is recommended as a way to find the number of factors when the items are ordinal. The lowest value indicates the best number of factors.

include reference on why imputation is better than removing observations, pairwise removing is biased, using means isn’t good.
Categorical missing values using multiple Correspondence Analysis (also called Missing Fuzzy Average method) Josseet al (2010)
This function tests whether a correlation matrix is significantly different from an identity matrix (Bartlett, 1951). If the Bartlett’s test is not significant, the correlation matrix is not suitable for factor analysis because the variables show too little covariance.
This is a test that the matrix is an identity matrix. This would mean that the correlations were not significantly different from 0. If it’s not significant, the matrix is not suitable because the variables show too little covariance.
The chi-squared for the Bartlett test is 6.5696263^{4} with 2278 DF, p = 0e+00.
From EFAtools::KMO documentation:
The KMO represents the degree to which each observed variable is predicted by the other variables in the dataset and with this indicates the suitability for factor analysis
The numeric version of the dataset is used because stats::cor is used to find the correlation and it requires numeric input. Used option for Spearman correlation because of ordered variables.
## ℹ 'x' was not a correlation matrix. Correlations are found from entered raw data.

For factor analysis, it is recommended that some of the item
correlationsshould be between 0.3 and 0.9. Polyserial correlations were
computed using the lavCor function in the
lavaan package in R with options for ordered factors and
pairwise handling of missing values. Pairwise deletion of missing values
means that individuals with some missing data are not dropped; their
data is used when available.
The minimum correlation in this data set is -0.7175318. The maximum correlation in this data set is 0.8879515.
#### Post-Imputation
The post imputation polyserial correlation was also computed using
the lavcor function, but with no setting for missing values
since they were imputed and cor.smooth = TRUE to avoid having a
non-positive-definite matrix to work on in future steps.
The minimum correlation was -0.6908209. The maximum correlation was 0.8870493.
From the EFAtools documentation:
Various methods for performing parallel analysis. This function uses future_lapply for which a parallel processing plan can be selected. To do so, call library(future) and, for example, plan(multisession); see examples.
Settings Used:
- n.obs = 1117 - eigen_type = “EFA” - fa = “fa” (factor analysis not
PCA) - fm = “wls” (weighted least squares because pa gave errors and
weighted recommended for ordinal data. - use = “all.obs” (since we have
imputed missing values, we can use all data points) - cor = “poly” (use
polychoric correlation matrix) - n.iter = 100 (run for 100
iterations)
The suggested number of factors is 16.
MAP is recommended as a way to find the number of factors when the items are ordinal. The lowest value indicates the best number of factors.

Categorical missing values using multiple Correspondence Analysis (also called Missing Fuzzy Average method) Josseet al (2010)
This function tests whether a correlation matrix is significantly different from an identity matrix (Bartlett, 1951). If the Bartlett’s test is not significant, the correlation matrix is not suitable for factor analysis because the variables show too little covariance.
This is a test that the matrix is an identity matrix. This would mean that the correlations were not significantly different from 0. If it’s not significant, the matrix is not suitable because the variables show too little covariance.
The chi-squared for the Bartlett test is 6.7613184^{4} with 2415 DF, p = 0e+00.
From EFAtools::KMO documentation:
The KMO represents the degree to which each observed variable is predicted by the other variables in the dataset and with this indicates the suitability for factor analysis
The numeric version of the dataset is used because stats::cor is used to find the correlation and it requires numeric input. Used option for Spearman correlation because of ordered variables.

For factor analysis, it is recommended that some of the item
correlationsshould be between 0.3 and 0.9. Polyserial correlations were
computed using the lavCor function in the
lavaan package in R with options for ordered factors and
pairwise handling of missing values. Pairwise deletion of missing values
means that individuals with some missing data are not dropped; their
data is used when available.
The minimum correlation in this data set is -0.717518. The maximum correlation in this data set is 0.8872086.
#### Post-Imputation
The post imputation polyserial correlation was also computed using
the lavcor function, but with no setting for missing values
since they were imputed and cor.smooth = TRUE to avoid having a
non-positive-definite matrix to work on in future steps.
The minimum correlation was -0.6908064. The maximum correlation was 0.8850145.
From the EFAtools documentation:
Various methods for performing parallel analysis. This function uses future_lapply for which a parallel processing plan can be selected. To do so, call library(future) and, for example, plan(multisession); see examples.
Settings Used:
- n.obs = 1117 - eigen_type = “EFA” - fa = “fa” (factor analysis not
PCA) - fm = “wls” (weighted least squares because pa gave errors and
weighted recommended for ordinal data. - use = “all.obs” (since we have
imputed missing values, we can use all data points) - cor = “poly” (use
polychoric correlation matrix) - n.iter = 100 (run for 100
iterations)
The suggested number of factors is 16.
MAP is recommended as a way to find the number of factors when the items are ordinal. The lowest value indicates the best number of factors.

include reference on why imputation is better than removing observations, pairwise removing is biased, using means isn’t good.
Categorical missing values using multiple Correspondence Analysis (also called Missing Fuzzy Average method) Josseet al (2010)
This function tests whether a correlation matrix is significantly different from an identity matrix (Bartlett, 1951). If the Bartlett’s test is not significant, the correlation matrix is not suitable for factor analysis because the variables show too little covariance.
This is a test that the matrix is an identity matrix. This would mean that the correlations were not significantly different from 0. If it’s not significant, the matrix is not suitable because the variables show too little covariance.
The chi-squared for the Bartlett test is 6.5549798^{4} with 2278 DF, p = 0e+00.
From EFAtools::KMO documentation:
The KMO represents the degree to which each observed variable is predicted by the other variables in the dataset and with this indicates the suitability for factor analysis
The numeric version of the dataset is used because stats::cor is used to find the correlation and it requires numeric input. Used option for Spearman correlation because of ordered variables.
## ℹ 'x' was not a correlation matrix. Correlations are found from entered raw data.

For factor analysis, it is recommended that some of the item
correlationsshould be between 0.3 and 0.9. Polyserial correlations were
computed using the lavCor function in the
lavaan package in R with options for ordered factors and
pairwise handling of missing values. Pairwise deletion of missing values
means that individuals with some missing data are not dropped; their
data is used when available.
The minimum correlation in this data set is -0.7175082. The maximum correlation in this data set is 0.8881154.
#### Post-Imputation
The post imputation polyserial correlation was also computed using
the lavcor function, but with no setting for missing values
since they were imputed and cor.smooth = TRUE to avoid having a
non-positive-definite matrix to work on in future steps.
The minimum correlation was -0.6902317. The maximum correlation was 0.8871507.
From the EFAtools documentation:
Various methods for performing parallel analysis. This function uses future_lapply for which a parallel processing plan can be selected. To do so, call library(future) and, for example, plan(multisession); see examples.
Settings Used:
- n.obs = 1117 - eigen_type = “EFA” - fa = “fa” (factor analysis not
PCA) - fm = “wls” (weighted least squares because pa gave errors and
weighted recommended for ordinal data. - use = “all.obs” (since we have
imputed missing values, we can use all data points) - cor = “poly” (use
polychoric correlation matrix) - n.iter = 100 (run for 100
iterations)
The suggested number of factors is 16.
MAP is recommended as a way to find the number of factors when the items are ordinal. The lowest value indicates the best number of factors.

Categorical missing values using multiple Correspondence Analysis (also called Missing Fuzzy Average method) Josseet al (2010)
This function tests whether a correlation matrix is significantly different from an identity matrix (Bartlett, 1951). If the Bartlett’s test is not significant, the correlation matrix is not suitable for factor analysis because the variables show too little covariance.
This is a test that the matrix is an identity matrix. This would mean that the correlations were not significantly different from 0. If it’s not significant, the matrix is not suitable because the variables show too little covariance.
The chi-squared for the Bartlett test is 6.6065968^{4} with 2278 DF, p = 0e+00.
From EFAtools::KMO documentation:
The KMO represents the degree to which each observed variable is predicted by the other variables in the dataset and with this indicates the suitability for factor analysis
The numeric version of the dataset is used because stats::cor is used to find the correlation and it requires numeric input. Used option for Spearman correlation because of ordered variables.
## ℹ 'x' was not a correlation matrix. Correlations are found from entered raw data.

For factor analysis, it is recommended that some of the item
correlationsshould be between 0.3 and 0.9. Polyserial correlations were
computed using the lavCor function in the
lavaan package in R with options for ordered factors and
pairwise handling of missing values. Pairwise deletion of missing values
means that individuals with some missing data are not dropped; their
data is used when available.
The minimum correlation in this data set is -0.7175949. The maximum correlation in this data set is 0.8888165.
#### Post-Imputation
The post imputation polyserial correlation was also computed using
the lavcor function, but with no setting for missing values
since they were imputed and cor.smooth = TRUE to avoid having a
non-positive-definite matrix to work on in future steps.
The minimum correlation was -0.6902169. The maximum correlation was 0.8867879.
From the EFAtools documentation:
Various methods for performing parallel analysis. This function uses future_lapply for which a parallel processing plan can be selected. To do so, call library(future) and, for example, plan(multisession); see examples.
Settings Used:
- n.obs = 1117 - eigen_type = “EFA” - fa = “fa” (factor analysis not
PCA) - fm = “wls” (weighted least squares because pa gave errors and
weighted recommended for ordinal data. - use = “all.obs” (since we have
imputed missing values, we can use all data points) - cor = “poly” (use

Categorical missing values using multiple Correspondence Analysis (also called Missing Fuzzy Average method) Josseet al (2010)
This function tests whether a correlation matrix is significantly different from an identity matrix (Bartlett, 1951). If the Bartlett’s test is not significant, the correlation matrix is not suitable for factor analysis because the variables show too little covariance.
This is a test that the matrix is an identity matrix. This would mean that the correlations were not significantly different from 0. If it’s not significant, the matrix is not suitable because the variables show too little covariance.
The chi-squared for the Bartlett test is 6.2748245^{4} with 2080 DF, p = 0e+00.
From EFAtools::KMO documentation:
The KMO represents the degree to which each observed variable is predicted by the other variables in the dataset and with this indicates the suitability for factor analysis
The numeric version of the dataset is used because stats::cor is used to find the correlation and it requires numeric input. Used option for Spearman correlation because of ordered variables.
## ℹ 'x' was not a correlation matrix. Correlations are found from entered raw data.

For factor analysis, it is recommended that some of the item
correlationsshould be between 0.3 and 0.9. Polyserial correlations were
computed using the lavCor function in the
lavaan package in R with options for ordered factors and
pairwise handling of missing values. Pairwise deletion of missing values
means that individuals with some missing data are not dropped; their
data is used when available.
The minimum correlation in this data set is -0.7175873. The maximum correlation in this data set is 0.8916518.
#### Post-Imputation
The post imputation polyserial correlation was also computed using
the lavcor function, but with no setting for missing values
since they were imputed and cor.smooth = TRUE to avoid having a
non-positive-definite matrix to work on in future steps.
The minimum correlation was -0.6902439. The maximum correlation was 0.8921351.
From the EFAtools documentation:
Various methods for performing parallel analysis. This function uses future_lapply for which a parallel processing plan can be selected. To do so, call library(future) and, for example, plan(multisession); see examples.
Settings Used:
- n.obs = 1117 - eigen_type = “EFA” - fa = “fa” (factor analysis not
PCA) - fm = “wls” (weighted least squares because pa gave errors and
weighted recommended for ordinal data. - use = “all.obs” (since we have
imputed missing values, we can use all data points) - cor = “poly” (use
polychoric correlation matrix) - n.iter = 100 (run for 100
iterations)
The suggested number of factors is 15.
MAP is recommended as a way to find the number of factors when the items are ordinal. The lowest value indicates the best number of factors.

include reference on why imputation is better than removing observations, pairwise removing is biased, using means isn’t good.
Categorical missing values using multiple Correspondence Analysis (also called Missing Fuzzy Average method) Josseet al (2010)
This function tests whether a correlation matrix is significantly different from an identity matrix (Bartlett, 1951). If the Bartlett’s test is not significant, the correlation matrix is not suitable for factor analysis because the variables show too little covariance.
This is a test that the matrix is an identity matrix. This would mean that the correlations were not significantly different from 0. If it’s not significant, the matrix is not suitable because the variables show too little covariance.
The chi-squared for the Bartlett test is 6.6272065^{4} with 2278 DF, p = 0e+00.
From EFAtools::KMO documentation:
The KMO represents the degree to which each observed variable is predicted by the other variables in the dataset and with this indicates the suitability for factor analysis
The numeric version of the dataset is used because stats::cor is used to find the correlation and it requires numeric input. Used option for Spearman correlation because of ordered variables.
## ℹ 'x' was not a correlation matrix. Correlations are found from entered raw data.

For factor analysis, it is recommended that some of the item
correlationsshould be between 0.3 and 0.9. Polyserial correlations were
computed using the lavCor function in the
lavaan package in R with options for ordered factors and
pairwise handling of missing values. Pairwise deletion of missing values
means that individuals with some missing data are not dropped; their
data is used when available.
The minimum correlation in this data set is -0.717562. The maximum correlation in this data set is 0.8902964.
#### Post-Imputation
The post imputation polyserial correlation was also computed using
the lavcor function, but with no setting for missing values
since they were imputed and cor.smooth = TRUE to avoid having a
non-positive-definite matrix to work on in future steps.
The minimum correlation was -0.6902379. The maximum correlation was 0.8890639.
From the EFAtools documentation:
Various methods for performing parallel analysis. This function uses future_lapply for which a parallel processing plan can be selected. To do so, call library(future) and, for example, plan(multisession); see examples.
Settings Used:
- n.obs = 1117 - eigen_type = “EFA” - fa = “fa” (factor analysis not
PCA) - fm = “wls” (weighted least squares because pa gave errors and
weighted recommended for ordinal data. - use = “all.obs” (since we have
imputed missing values, we can use all data points) - cor = “poly” (use
polychoric correlation matrix) - n.iter = 100 (run for 100
iterations)
The suggested number of factors is 15.
MAP is recommended as a way to find the number of factors when the items are ordinal. The lowest value indicates the best number of factors.

Categorical missing values using multiple Correspondence Analysis (also called Missing Fuzzy Average method) Josseet al (2010)
This function tests whether a correlation matrix is significantly different from an identity matrix (Bartlett, 1951). If the Bartlett’s test is not significant, the correlation matrix is not suitable for factor analysis because the variables show too little covariance.
This is a test that the matrix is an identity matrix. This would mean that the correlations were not significantly different from 0. If it’s not significant, the matrix is not suitable because the variables show too little covariance.
The chi-squared for the Bartlett test is 6.7421286^{4} with 2346 DF, p = 0e+00.
From EFAtools::KMO documentation:
The KMO represents the degree to which each observed variable is predicted by the other variables in the dataset and with this indicates the suitability for factor analysis
The numeric version of the dataset is used because stats::cor is used to find the correlation and it requires numeric input. Used option for Spearman correlation because of ordered variables.
## ℹ 'x' was not a correlation matrix. Correlations are found from entered raw data.

For factor analysis, it is recommended that some of the item
correlationsshould be between 0.3 and 0.9. Polyserial correlations were
computed using the lavCor function in the
lavaan package in R with options for ordered factors and
pairwise handling of missing values. Pairwise deletion of missing values
means that individuals with some missing data are not dropped; their
data is used when available.
The minimum correlation in this data set is -0.7175677. The maximum correlation in this data set is 0.8898946.
#### Post-Imputation
The post imputation polyserial correlation was also computed using
the lavcor function, but with no setting for missing values
since they were imputed and cor.smooth = TRUE to avoid having a
non-positive-definite matrix to work on in future steps.
The minimum correlation was -0.6902114. The maximum correlation was 0.8877677.
From the EFAtools documentation:
Various methods for performing parallel analysis. This function uses future_lapply for which a parallel processing plan can be selected. To do so, call library(future) and, for example, plan(multisession); see examples.
Settings Used:
- n.obs = 1117 - eigen_type = “EFA” - fa = “fa” (factor analysis not
PCA) - fm = “wls” (weighted least squares because pa gave errors and
weighted recommended for ordinal data. - use = “all.obs” (since we have
imputed missing values, we can use all data points) - cor = “poly” (use
polychoric correlation matrix) - n.iter = 100 (run for 100
iterations)
The suggested number of factors is 15.
MAP is recommended as a way to find the number of factors when the items are ordinal. The lowest value indicates the best number of factors.
